Socket Head Cap Screw
A Socket Head Cap Screw, also known as a Hex Bolt or Allen Screw, is one of the most popular fasteners in industrial applications and assembly lines. They are incredibly strong (link to our tensile strength and torque specification chart), inexpensive, and easy to install using a hex wrench or socket head cap wrench.
The head of a socket cap screw sits in a countersunk hole, flush with the surface it's mounted on. This prevents protrusions that could be damaged or cause injury and enables the screw to be driven by a hex wrench. This drive style is a good alternative to slotted or Phillips screws that can be more prone to stripping. They can also be used as a pivot point or axle because their shoulders are ground to a tight tolerance.
These fasteners are available in a wide range of sizes and materials. They are cold formed and then threaded either by cutting or rolling, which essentially presses the threads into the screw without removing any material. They may also undergo heat treatment to increase tensile strength and hardness.
Socket head caps have a low profile, meaning they can be installed in spaces where nuts or bolts can't. When paired with a hex key, these products can be installed or removed in seconds.
These types of fasteners are often used in the automotive industry because they have high tensile strengths and are ideal for heavy-duty projects. They are also favored in structural applications because of their durability and resistance to corrosion and high temperatures. Socket Head Cap Screw
